Despite of personal issues, Majestic Software have progressed on their internal developments for their future Training Edition of the Q400 complex simulation in P3D.
In this post, you will find many information on the features to be included. They are also mentioning the Cockpit Edition to include Training Edition features PLUS multi-monitor support and touchscreen functionality.
For the Q300 project, they are holding it until the new simulators get out and are stable (P3D V5, Microsoft Flight Simulator).
In another post specific to P3D5, they confirmed that a free upgrade for P3D registered users will be necessary but for minor bugs. You can already fly with it without visible and big troubles.
